Abrasive blast cleaning encompasses a variety of methods that include the use of several types of media propelled by water or air. The abrasives media vary widely, from Rice Hulls and Walnut Shells to various Slag, Garnet and Steel Shot. Typical blast cleaning minerals include Olivine, Specula, Hematite and Garnet. Man-made media used for blast cleaning include Plastic, Coated Minerals, Recycled Glass, Steel Shot, Coal Slag, Copper Slag and Nickel Slag.

For over 50 years, silica sand had been forbidden to use in blasting because it causes Silicosis disease and it is very dangerous for human health. Nowadays the Copper Slag is much more economical, healthy and easy to use.

Silicosis is a form of Occupational Lung Disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in forms of nodular lesions in the upper lobes of the lungs. It is a type of pneumoconiosis, from pneumo (lung) and konis (dust).

Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis.

Silicosis that develops 5–10 years after first exposure to higher concentrations of silica dust.Symptoms and X-Ray findings are similar to chronic simple silicosis, but occur earlier and tend to progress more rapidly. Patients with accelerated silicosis are at greater risk for complicated disease, including progressive massive fibrosis (PMF).

Nozzle size

faq7 Nozzle size should be in relation to the capacity of the compressor. Note that at continuous working the compressor should not run at more than 5% of the capacity.

Nozzle pressure

faq8 Air Pressure at the nozzle should be between 80 and 100 psi (closer to 100 psi cause the better performance). Remember to achieve high nozzle pressure. Read More...

Nozzle direction

faq9 Avoid blasting perpendicular (90 degrees) to the surface. An angle of 75-80 degrees gives the best performance. Read More...

Air Hose

faq10 The air hose between compressor and blasting unit should be as large as possible and as short as possible. Read More...

Air / Grit mixture

faq11 The grit valve should be set at a lean feed. Too much grit in the air flow results in low production and less profile. Start with the grit valve closed, open gently until you get the proper effect and leave it there. The grit coming out of the nozzle should look like a blue haze and not like a black cloud.

Distance to Surface

faq12 Optimum distance between nozzle and surface is about 30 cm (12 inch). Read More...
